Description

Technical Field

[0001] The utility model relates to the technical field of screws, in particular to a screw that is easy to introduce. Background Art

[0002] Screws are a common fastener. They typically consist of a head and a shank, and come in a variety of shapes and sizes. They rotate into objects, tightly connecting different parts. They are widely used in machinery manufacturing, construction, and other fields. Their secure connection and ease of disassembly make them an indispensable component in modern industry.

[0003] Existing screws often tilt when being rotated into an object. Once tilted, they cannot be rotated smoothly, making it difficult to normally introduce the screw into the object. A stuck screw is not only difficult to enter the object, but also extremely difficult to pull out. If it is pulled out forcefully, the threads inside the screw hole will be damaged, making the screw hole unusable. Therefore, based on the above problems, a screw that is easy to introduce is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-6, a screw that is easy to introduce, includes a base block 1, a screw hole 10 is opened inside the base block 1, a stud 2 is arranged inside the screw hole 10, a first thread 11 is opened inside the screw hole 10, and a second thread 7 is opened on the surface of the stud 2, the first thread 11 and the second thread 7 are engaged with each other, and the stud 2 can be rotated inside the screw hole 10 by the mutual engagement of the first thread 11 and the second thread 7. When the stud 2 rotates inside the screw hole 10, the stud 2 moves along the screw hole 10 while rotating. A groove 9 is opened on the top of the stud 2, and the groove 9 is located at the center position of the top of the stud 2. The stud 2 can be easily rotated with a tool such as a screwdriver through the groove 9. A limit plate 8 is fixedly provided on the surface of the stud 2, and an auxiliary plate 5 is overlapped on the top of the limit plate 8. An auxiliary rod 4 is slidingly provided inside the auxiliary plate 5. The auxiliary rod The number of 4 is three, and the three auxiliary rods 4 are distributed in a circular array. The three auxiliary rods 4 can prevent the auxiliary plate 5 from tilting and improve stability. A support block 3 is fixed at the bottom of the auxiliary rod 4, which is convenient for introducing the screw. The support block 3 is aligned with the top of the screw hole 10, and the stud 2 is aligned with the screw hole 10. The rotating tool drives the stud 2 to rotate through the groove 9. The rotation of the stud 2 causes the second thread 7 to rotate on the surface of the first thread 11, thereby causing the stud 2 to move downward. The stud 2 is limited by the auxiliary plate 5 so that the stud 2 is vertically downward. The device can effectively prevent the screw from getting stuck due to tilting, ensure that the screw can always maintain the correct direction and be smoothly introduced into the interior of the object. The convenience and smoothness of the screw installation and introduction are improved through this device.

[0023] Specifically, a limiting sleeve 6 is fixedly provided on the top of the auxiliary rod 4. There are multiple limiting sleeves 6. The limiting sleeves 6 prevent the auxiliary plate 5 from sliding upward along the auxiliary rod 4 and finally falling off.

[0024] Specifically, the inner diameter of the auxiliary plate 5 is consistent with the diameter of the stud 2, and the inner diameter of the support block 3 is larger than the diameter of the limiting plate 8. The inner diameter of the auxiliary plate 5 is consistent with the diameter of the stud 2, so that the auxiliary plate 5 can effectively move the stud 2 in the correct posture. The inner diameter of the support block 3 is larger than the diameter of the limiting plate 8, which can prevent the support block 3 from hindering the movement of the stud 2 and the limiting plate 8.

[0025] Specifically, the top of the screw hole 10 is trumpet-shaped, and the bottom of the stud 2 is cone-shaped, so that the stud 2 can be easily inserted into the screw hole 10 , and the support block 3 can be easily positioned through the top of the screw hole 10 .

[0026] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0027] During use: insert the support block 3 from above the stud 2, and the support block 3 moves downward to the bottom of the stud 2. At the same time, since the auxiliary plate 5 contacts the bottom of the limit plate 8, the support block 3 drives the auxiliary rod 4 to slide inside the auxiliary plate 5. After the installation is completed, the support block 3 is overlapped at the opening of the screw hole 10, and the tool is inserted into the groove 9. The rotating tool drives the stud 2 to rotate through the groove 9. The rotation of the stud 2 drives the second thread 7 to rotate on the surface of the first thread 11, thereby making the stud 2 move downward inside the screw hole 10. During the downward movement of the stud 2, the surface of the stud 2 is supported by the auxiliary plate 5, so that the stud 2 is in a vertical state and moves downward. After the installation is completed, pull the auxiliary plate 5 upward, so that the auxiliary plate 5 drives the auxiliary rod 4 and the support block 3 to move upward and be removed from the stud 2.

[0028] To sum up, the screw is easy to introduce, align the support block 3 with the top of the screw hole 10, and align the stud 2 with the screw hole 10, and the rotating tool drives the stud 2 to rotate through the groove 9. The rotation of the stud 2 causes the second thread 7 to rotate on the surface of the first thread 11, thereby causing the stud 2 to move downward, and the stud 2 is limited by the auxiliary plate 5 so that the stud 2 is vertically downward. The device can effectively prevent the screw from getting stuck due to tilting, ensure that the screw can always maintain the correct direction, and be smoothly introduced into the interior of the object. The convenience and smoothness of the screw installation and introduction are improved through this device.
